Khapra Beetle

Rearing experiments with Trogoderma granarium Everts were conducted to determine why the larvae fail to develop in certain pulses. The larvae were unable to penetrate whole grains of any of the nine pulses tested. In flour form, the pulses fell into three main groups. On flours of green, black, Bengal and kabuli grams, and cowpea and pigeon pea, development was as successful and rapid, or nearly so, as on wheat flour and showed little improvement from the addition of yeast. Development on flours of soybean and lentil was markedly slower, and showed marked improvement when yeast was added. By adding increased proportions of balanced diet, it was shown that the performance of larvae on soybean, lentil and even on French bean flours could be improved, but with the last two was not as good as with cellulose. It is concluded that lentils and French beans lack essential nutrients and may also contain a growth inhibitor.

Abstract A series of tests was performed to examine the development ability of Trogoderma granarium Everts on six different sorghum milling fractions: bran, shorts, coarse grits, fine grits, red dogs, and flour. In the first bioassay, 20 adults and 20 g of each fraction were placed in vials of 60 ml at 30°C and 60% relative humidity for a period of 65 d. In the second part of the experiment, a neonate larva (1-d old) was placed in vials with 1 g of each fraction and exposed at 25, 30, and 32°C until adult emergence. Significantly more live larvae were found in bran compared with flour and to the two grain controls (soft wheat and whole wheat flour), where most dead adults were recorded. The increase in temperature reduced both the time to adult emergence and larval mortality before the appearance of the first adult. Developmental times ranged between 25.5 and 37.5 d, and 23.2 and 29.0 d for 30 and 32°C, respectively. At 25°C, larvae in the milling fractions did not reach 100% adult emergence even after almost 3 mo. However, the first adult appeared in the shorts fraction at all temperatures tested. Our results show that all sorghum milling fractions support the development of T. granarium and that the optimal temperatures for growth and development are 30 and 32°C. These results also have important implications for phytosanitary regulations and international trade, given the quarantine restrictions on this insect.

It is possible to raise healthy generations by improving the awareness levels of the role models (parents, teachers etc.) who will shape the perspectives of future parents towards nutrition and physical activity. That children receive adequate levels of nutrition from proper sources, which is vital for children’s growth and development, is considerably under the control of external factors (e.g. family and friends’ eating habits, third person’s care/knowledge and experiences such as teachers/trainers etc.). Considering nutrition and the intense physical activity of preschoolers, which is an inherent characteristic of that development stage, and especially the children who are guided to do more intense physical activity, the case becomes more complex. Thus, with the aim to address children’s energy depletion from intense physical activity, it is suggested to provide children with attractive alternatives. Including some of these alternatives, this study aims to reveal the significance of an adequate and balanced diet as well as proper planning of physical activity and periodic assessments at the appropriate time and conditions so that the children who start regular physical activity display optimal performance.
